The limiting velocity criteria are generally adopted in the city sewer designing to control the sediment deposition in the pipe.
城市排水管道设计中，普遍采用最小流速准则控制排水管道中的泥沙淤积。

Based on the analysis of the equation and condition, the starting current velocity formula about the pill sediment is further proved.
通过该方程与水沙条件的分析，进一步验证了散粒体泥沙起动的流速公式。
